SEAT FOR HARVESTERS OR THE LIKE.

"TCIFICATION forming' part of Letters PatentNo. 683,675, dated October 1, 1901. Y

Application filed May 8. 1901. Serial No. 59,204.V (No model.)

. whom t may concern.- ie it known that I, HENRY W. AVERY, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Seats for Harvesters or the Like, (Case A,) of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to pressed-steel seatssuch as are used on harvester-s, cnltivators, hay1'akes,and various agriculturalmachines. Its object is tol provide a seat which while being simple in construction shall have the metal disposed where it is most needed, so that an equally strong seat may be made from less material, thereby reducing the cost.

These seats are commonly supported centrally on a suitable spring-bar, and the tendency to break comes at the center portion adjacent to the support. To strengthen the seat at thispoint, it has been customary to corrugate it; but as in stamping sheets of sheet metal it is impracticable to`have the.

original sheet thicker at one point than another the whole seat-has been made heavier than is necessary, so as to have the right thickness for this center portion. The pres. ent invention is designed to overcome this, providing a simple and eflicient reinforcingplate at the center, which 'shall so strengthen the seat at this point that the total weight of the seat and the reinforcing may be less than the corrugated seat alone. In applying this reinforcing I employ the same rivets to hold it to the seat and to form stops for the supporting-bar. No extra rivets beyond those necessary to define the position of the supporting-bar are employed to hold the reinforcing in place, or, stated conversely, no extra rivets beyond those necessary to hold the reinforcing in place are necessary to define the supporting-bar. This conjoint double action of the rivet-s is what allows the seat to be produced with the necessary clieapness, and it is an essential element of my invention.

Figure l is a bottom plan of the seat and its supporting-spring. Fig. 2 is a vertical section thereof on the line 2 2 of Fig. l, and Fig. 3 is a fragmentary cross-section on the line 3 3 of Fig. l.

Referring to the parts by letters, A represents the seat proper, which is stamped from a single piece of sheet metal and is lightened by suitable openings, as a. tion a of this seat is fiat, and directly beneath this portion is the reinforcing-plate B, which is preferably circular, as shown. This reinforce is secured to the seat by the rivets C, of which there are preferably four. These rivets securely hold the reinforcing to the seat, while theirdownwardly-projecting heads form stops limiting the supporting-bar D. There being four rivets employed at the four corners at an imaginary square, the bar D may extend either in the direction shown in the drawings or at right angles thereto and be f defined in position in either event. The bar is held in place by the bolt E taking through the seat proper, the reinforcing, and the bar and clamped with a nut e.

The seat proper may be made of very light sheet material, and the reinforcing of other sheet Vmaterial of the proper thickness, so that the total .Weight is disposed where it is most efficient. The rivets C being nearly flat on the top are not objectionable to the rider, and they are very easily applied.

l. A seat madeY of sheet metal and reinforced by a plate held to the seat by rivets which have downwardly-projecting heads adapted to abut a supporting-bar, substantially as described.

2. A seat made of sheet metal and reinforced by a plate held to the seat by a plurality of rivets,which rivets have downwardlyvextending heads and are adapted to have their inner sides engage the edges of a supporting-bar beneath the seat, substantially as described.

3. The combination of a sheet-metal seat proper having a at central portion, a fiat restops for a supporting-bar abuttin'g their in'-Y inforcing-plate directly beneath said central ner sides, substantially as described. 1d portion, and rivets projecting through the In testimony whereof I hereunto affix my reinforcing-plate and the seat and havingy signature in the presence of two witnesses.y
